Professor Sausages — Trust & Verification MCP server

• address_screenFree

  Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent all-clear. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• domain_intelFree

  RDAP registration card for a domain (creation/expiry dates, registrar, statuses, nameservers, DNSSEC) plus derived risk flags like domain age. view='dns' returns a live multi-record DNS summary (A/AAAA/CNAME/MX/NS/TXT/SOA/CAA + SPF/DMARC); view='live' re-reads the registry at the moment you ask. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• email_checkwrite actionFree

  Deliverability signals for one address: RFC5322 syntax, live MX/SPF/DMARC over DNS-over-HTTPS, disposable/role-account flags. Signals with evidence — not a guaranteed inbox verdict. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• find_dataFree

  Describe the data you need in plain language (e.g. 'Apple risk factors 2023', 'is this token a honeypot', 'is this email deliverable', 'read this page'). Searches this server's datasets first, then the whole Professor Sausages catalog, and returns matching endpoints with method, URL, price, and how to call them. Free.

• iban_checkFree

  Validate an IBAN (length + mod-97 check digits). view='decode' resolves it to country, bank and account parts; view='format' returns electronic and paper (grouped) forms. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• phone_checkFree

  Validate and normalize a phone number: E.164 form, line type, region, and a verdict. Pure CPU, no third-party lookup. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• pricingFree

  Every endpoint this server fronts, with its exact per-call USD price (x402, USDC on Base) and a one-line summary, read live from the route table. Free.

• request_dataFree

  The suggestion box: ask for data we don't have (a pre-2015 filing, an uncovered ticker, an unsupported chain, a whole dataset). Requests feed the nightly ingestion queue — filings are usually available within ~24h. Include contact if you want to hear back. Free.

• sanctions_entityFree

  The complete OFAC record for one entity number: all aliases, addresses, sanctions programs, and extracted identifiers (passports, tax ids, DOBs). Use after sanctions_screen returns a candidate. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• sanctions_screenFree

  Fuzzy-screen a name against the full OFAC SDN + Consolidated lists. Returns match / possible_match / no_match with scored candidates and the aliases that matched — never a silent all-clear. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• url_screenFree

  Screen a URL against the URLhaus blocklist snapshot plus deterministic live heuristics (redirect chain, host reputation signals, lookalike patterns). Returns a verdict with the rules that fired. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

• vessel_screenFree

  Screen vessels against OFAC maritime designations by fuzzy name, exact call sign, or IMO number, with flag filtering. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
